Pur osc <br />The purpose of th1- report <br />and Wetland Managemavit Plan <br />aforementioned problems. <br />EXISTING t•ACILITIE5 <br />1. Storm Sewers <br />is to propose a storm water <br />that will solve the <br />The existing storm sever syctrm cons <br />approximately of <br />approximately 15.4 miles of concrete and corrugated <br />metal pipe. The storm sewers vary in size from 12" <br />diamot.•r to 54" diameter. The replacement cost of the <br />storm sewer system at $45.00 per foot is $3.6 million. <br />The actual replacement cost would he higher because <br />roads would also need to be reconstructed. <br />2. Ditches <br />A majority of tPIe storm sewers empty into ditches which <br />ultimately carry the water to Rice Crcek. The combinrm ed <br />length of the ditches that carry <br />outlets to the City limits is approximately 1.3 miles. <br />wetlands <br />in December of 1981, Ramsey Soil and Water Consveration <br />District completed a Wetland Inventory for the City of <br />Mounds View. This inventory indicates that there are <br />219.5 acres of wetlands in the City of Mounds View. <br />This is approximately 8 percent of the land within the <br />City limits (219.5 acres/2,80U acresl. Wetlands vary in <br />B 12N from 0.9 acr.es to 62.7 acres. <br />POSSIBLE. SOLUTIONS <br />1. Storm__. Sewer Mal^tenance <br />Storm sewer maintenance includes repairinq broken pip, <br />joints, cleaning catrh basins, excavatinn sediment at <br />storm sewer pipe outlets, removing large stones, boards <br />and branches from Sturm sewer and cleanin., storm sewer: <br />once every 2 or 3 years. <br />MM <br />
